MATCHING-PLANE.

SPECIFICATION forming part of Letters Patent No. 748,199, dated December29, 1903.

Application filed March 20, 1903.

To aZZ whom it may concern:

Be it known that I, ALEXANDER MASON, a citizen of the United States,residing at Salem,- in the county of Essex and State of Massachusetts,have invented certain new and useful Improvements in Matching-Planes;and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to matching-planes; and it consists in the novelconstruction and combination of the parts hereinafter fully describedand claimed.

In the drawings, Figure l is a side view of the matching-plane. Fig. 2is a cross-section taken on the line as w in Fig. 1. Fig. 3 is a partialplan view showing the clamping-levers and looking in the direction ofthe arrow y in Fig. l.

A is the body of the plane, provided with a handle B at one end and aknob O at the other end. The body portion A has a broad groove b and anarrow groove 0 in its under side, and D is a longitudinal rib on theupper side of the body portion.

E is an inclined support for the blades, which also projects on theupper side of the body portion,and (i represents slots or notches in thebody portion A for the blades to project through.

F isasingle cutting-blade, and G isa forked cutting-blade. These bladesare laid upon the support E, one on each side of the rib D, and areclamped in position by means of two clamping-levers f and g, which arepivoted on the end portions of a pin H, which is secured in the rib D.These clamping-levers are provided at their upper ends with thumbsorewsf and g, which bear against the Serial No. 148.745. (No model.)

provided with projecting brackets 7; at its end and middle portions. Theend brackets carry bars J, which are" slidable in guideholes j in thebody of the plane. The middle bracket carries a bar K, which is slidablein a hole 70 in the body of the plane and which is provided with aseries of cross-holes m.

M is a spring-pressed stop-pin which is slidable in a lug n on the bodyof the plane and which engages with the said cross-holes. The guide isslid so as to suit the work, and it is then secured in positionby meansof the said stop-pin.

The two blades form three separate outters, and they will tongue andgroove boards of widely-varying thickness in a very satisfactory manner.

What I claim is In a matching-plane, the combination, with abodyportion', of a guide for the said body portion provided withprojecting brackets at its middle and end portions, bars projecting fromthe said end brackets and slidable in cross-holes in the said bodyportion, a bar projecting from the middle bracket and provided with aseries of cross-holes and slidable in a hole in the said body portion,and aspringactuated stop-pin carried by the said body portion andengaging with the cross-holes of the said bar.

In testimony whereof I affix my signature in presence of two witnesses,

, ALEXANDER MASON.
